3 Claims.

It is the object of this invention to provide a novel and inexpensivemattress of the` type having edge rolls which 'are concealed Within thmattress.

Al particular object is to provide in a mattress, having a padded innerspring body, edge rolls formed from portions of the top and bottompadding/material and so connected tothe spring body and boxing thatseparation of the rolls from the 19 padding is effectively guardedagainst.I

Another object is to provide a mattress having edge rolls which areformed and attached to the boxing by stitches entirely concealed withinthe mattress.

1;, A further object is to provide a novel method of forming a mattresswhereby economies in the manufacturing operation and in the use offabrics are eiected and internal edge rolls are so formed as to leavethe boxing and top and bottom.tick

ing smooth and without indentations.

The invention will be best understood by reference to the accompanyingdrawings in which,

, Figure 1 is a fragmentary, vertical section through the spring bodyand inner lining fabric 2;, and layers of padding and illustrating mypreferred methodof forming the edge rolls;

Fig. 2 is a similar section with the boxing applied to the filling body;

Fig. 3 is a plan view, partially broken away,

showing a part of the filling and corner roll before the application ofthe boxing, and

Fig. 4 is a part vertical section and part elevation illustrating thecompleted mattress;

A spring body of common or suitable type constitutes the principalfilling for the mattress. As

' illustrated, this body comprises a multiplicity of upholstery springs5 connected together at the margins of the mattress by helical springs 6and Within the body by helical springs 1 (Figs. 1 and 4,0y 3) extendingparallel to each other. Upon the top and bottom surfaces of the springbody are laid lining sheets IlA of suitable fabric. Ihese sheets have agreater superficial area than the spring body so that the marginalportions of '45 each sheet are adapted to be utilized in forming edgerolls 9 extending around the mattress for squaring the top and bottomcorners. Layers' of padding I0 are placed onthe outer surfaces of thesheets 8 respectively and are made to project 50 at the edgessufficiently to afford the stuffing for the corner rolls 9. Theprojecting edge portions of the padding I0 are then compressed andconfined by rolling over the edges of the sheets 8 and by applying tiesII extending through said lin- 55' ing sheets and padding I0 andengaging the marquired for the edge rolls.

ginal springs. 5 and 6. n this manner the rolls 9 are made integral withthe padding I0 and sheets 8 and in the same operation the rolls aresecured in proper position for direct support 'from the marginal springs5. 5

'Ihe resulting structure is ready for the application ofthe boxing, asillustrated in Fig. 2. The boxing comprises an outer ticking strip y I2,an inner fabric strip I3 and suitable quilting formed by stuffingmaterial I4 and parallel rows 10 of stitches I5 extending horizontallyaround the mattress. To attach the boxing to the previously formedstructure, rows of stitches I6 are applied to connect the upper andlower edges of the strip I3 to the upper and lower edge rolls 9 l5respectively. It will be understood that the outer strip I2 is separablefrom the upper and lower l margins of the strip I3 to allow access tothe outer surface of the latter for the sewing of' the stitches I6. 20To complete the mattress, asv shown in Fig. 4,

additional layers of padding II are applied to the outer surfaces of thepadding I0 and then the top and bottom ticking or cover sheets I8 areapplied and their edges secured to the upper'25 and lower edges of thestrip I2 by forming the usual or suitable seams I 9 while the outerboxing strip is placed under tension in its straight vertical position.

Among the advantages secured by my invenv30 tion,the following willnowbe understood. 'Ihe corner rolls are formed from integral portions ofthe top and bottom lining fabrics and padding material and such sheetsand padding are'essential irrespective of whether the edge rolls are '35provided. In other words, there are no extra. strips, sheets or separatebodies of filling re- The edge rolls are so confined directly betweenthe supporting springs and corners of the mattress that unusually square4 0 corners result and separation of the rolls fromA the top and bottompadding is rendered unlikely because of the unitary form of rolls andpadding. All stitches forming the corner rolls and connect ing the sameto the boxing and springare concealed within the mattress and the outersurfaces of the boxing and corner portions of the top 'and bottom areunusually straight and free from indentations.

Having described my invention, what I claim as new and desire to protectby Letters Patent 1s:

1. A mattress having in combination; abody of upholstery springsresiliently joined togetherl and having at its upper and lower marginsflexible tie members extending longitudinally of the vmargins andconstituting the sole connection' between springs around the' edges ofsaid body, a pair of lining sheets respectively overlying the top andunderlying the bottom of said body and each of said lining sheets havingaps adapted to project outward from said tie members, layers of loose,felt-like padding adjacent to said lining sheets, said flaps beingfolded upon the margins of said padding, ties passing through said flapsat a multiplicity of spaced points upon the outer margins of said layersof padding and engaging said longitudinally extending tie members andforming edge rolls from compressed integral edge portions of saidpadding material, a quilted boxing having inner and outer fabric stripswith padding between them, means connecting the upper and lower edgesrespectively of the inner strip of said boxing to said edge rolls andtop and bottom cover sheets having their edges secured Y' to the 'upperand lower edges respectively of said outer boxing strip. l

2. A mattress having in combination, a body of upholstery springsresiliently joined together and having at its upper and lower marginsiiexible tie members extending longitudinally of the margins andconstituting the sole connection between.springs around the edges ofsaid body, a pair of lining sheets respective/ly overlying the top andunderlying the bottom f said body and each of said lining sheets havingflaps adapted to project outward from said tie members, layers of loose,felt-like padding overlying the top and underlying the bottom vsurfaces,respectively of Y said lining sheets, said ilaps being folded upon themarginal portions of said padding, ties securlng said flaps at amultiplicity of spaced points upon the outer. margins of said layers ofpadding,

said ties passing through said flaps and margins and engaging saidlongitudinally extending tie members and forming edge rolls fromcompressed integral edge portions of said padding material, a

quilted boxing having inner and outer fabric strips 5 with paddingbetween them, means connecting the upper and lower edges respectively ofthe inner lof said boxing strips only to said edge rolls and top andbottom cover sheets having their edges secured to they upper and loweredges respectively of said outer boxing strip.

3. A mattress having in combination, a body of upholstery springsresiliently joinedtogether andhaving at its upper and lower marginsexible, helical springs extending longitudinally of 16 the margins, apair of lining sheets overlying the top and underlying the bottom ofsaid body directly and each having flaps adapted to project outward fromsaid helical springs, layers of loose padding overlying the top andunderlying the 20 bottom respectively of said lining.sheets, said y napsbeing folded to embrace the margins of said padding, ties securing saidaps upon the outer margins ofl said layers of padding and engaging saidhelical springs and forming edge rollsfrom 25.

compressed edge portions of said padding material directly above andbelow said helical springs, a quilted boxing having inner and outerfabric strips with padding between them, means conf necting the upperand lower edges respectively of said inner strip of said boxing to saidedge rolls, said inner fabric boxing strips being secured to saidouterboxing strips along lines extending parallel and adjacent to saidhelical springs and top and bottom cover sheets having their edgessecured to theupper and lower edges respectively of said outer boxingstrip.
